Patented oct. 10, 1950 NTOFFICE vvmnow Vincent Pampa'llona, New York,NY. Application MaylY, 1948. serial M12739;

4' Claims; (c1. 292-70) "Thfshfivntion is "an-intimation m1 art-or myapplication, Serial Number, 794 1832Qfi1ed06t'0'b'e'i 22, 19,46,nowabafi'idonedi' ,1

This invention relates td'iniprovementsin devices for holding "a movableher in adj listed positions rearward a stationary memb'erandmoreparticularly'to a device fo'r controlling the movements ofWindowsfslidable doors; and the like.

It is an object of-th-isinventioii'toprovide magnet means ror'eonrroningthe position of windows or other movable objects. The device is not onlyadaptedfor use on the ordinary window, but can'be effectively usedinshow cases, automobile windows, and in many-dther situations as willbe apparenttd persons skilled in the art.

There is now being produced a permanent mag;- net which is capable ofholding or pulling with a;'force-many'times'its wean-.1 one type ofmagnet, as Alni'c'o'fi s a composition of aluminum, nickel andcobaltlfand has very strong force exerohg'powis." It'"ia' further objectof the invention to apply a permanent magnet of the type denoted abovefor the purpose of holding windows in various positions.

A further object is the provision of a device for controlling theposition of a window, the device including a permanent magnet on thewindow sash and a strip of material attractable by the magnet, and meansto space the magnet from the strip to prevent direct contact of themagnet with the strip.

A further object is to provide a window holding device including apermanent magnet and a strip of material attractable by the magnet, andmeans to resiliently control the position of the magnet.

A further object is to provide in a magnet controlled window, detentmeans to hold the window fixed in predetermined positions.

These and other objects are attained by the novel construction andarrangement of parts hereinafter described and disclosed by theaccompanying drawing, forming a part hereof, and in which:

Fig. 1 is a side view of a section of a sash, with portions broken away,said portions carrying devices embodying the invention.

Fig. 2 is a sectional View taken on the line 22 of Fig. 1.

Fig. -3 is a perspective view of the magnet arrangement used in thedevice.

Fig. 4 is a front View of a plate of magnet attractable material used inthe device.

Referring to the drawings there is shown in Fig. 1 a window n ihavingatta'ched tfier' to an armatures as' a-strip"2 of metal at.tractableby amaign'et'; said strip having aplu rality' of holes"'Espacedat predetermined dis-'- tances from" each 'otherg" A" section aof a'"windowfsash1 has" a recess fi in which is positioned a'perm'anent'l'hagnet" E which is" preferably of the Alnicoftype bing formed from acomposition of aluminum, nickel andcobalt." However;"there areothe'rtypes or permanent magnets of great strength, recently developed, whichcan be used." Thel magnet shown in the drawing is of the horseslfoe'or'U-' shaped type and'the legs thereof pass through openings landB mffa'ate e which isattached by 'lnean'slof' screws or the like to'the'sash.The plated is made from a non-magnetic material such as stainlss'stelahd the magnet has no efiect thereon. 1 W

,Fixed to the legs of the'niaghet by me sf screws or the'like afesmallplates Ill madefrom, a non-magneticmaterial'such as stainless steel,

the plates extending through the apertures I and 8 in the plate 9. Theends of the plates ID are rounded as shown at H and project beyond thefree ends of the legs of the magnet, and engage the armature, such asthe strip 2 to space the magnet from the strip and prevent directcontact therewith.

This arrangement provides an air gap between the magnet and the stripand facilitates movement of the window.

Projecting from the plate 9 toward the rounded portion of the magnet isa pin l2 encircled by a away from the plate;

of the window is thus also facilitated.

Positioned in another recess [4 in the section: 4 is a detent whichcomprises a plate [5 having right angularly directed flanges l6 and IT,the plate being secured to the sash by means of screws or the like.

The flange H has an aperture through which. passes a detent bolt IS, thelatter passing also through a passage 19 in the sash. Positioned in. thepassage i9 and encircling the bolt I8 is a coiled sprin 20 which abuts adisc 2| on the bolt E8, the spring also abutting the flange ll andtending normally to move the bolt outwardly to enable it to enter one ofthe holes 3 in the strip 2. The bolt is also provided with a head 22 atone end thereof which engages the forked portion 23 of a curved handle24 by means of which the bolt can be retracted from the holes 3.

By means of this detent structure, the window can be fixed in definitepositions from the inside of a room so that it cannot be raised from theoutside. This provides safety from burglars and undesired intruders, atthe same time allowing the window to be opened to a certain height toallow the entrance of air for ventilating purposes. Also the window canbe adjusted to a position and held in such position but at a heightwhich will prevent small children from falling out while looking out ofthe window.

From the above description it will be seen that there has been provideda simple device for holding a window by means of a magnetic arrangementwithout necessitating the use of sash weights and cords. The permanentmagnets can be provided in many sizes to accommodate different sizes ofwindows.

It is obvious that the structure is not confined to use on windows butcan be effectively used in many places where one element is manuallymoved relative to another, such as show cases, garage doors, slidingdoors, desks, and the like.

The above description is to be considered as illustrative and notlimitative of the invention 01 which modifications can be made withoutdeparting from the spirit and scope of the appended claims.

The invention having been described, what is claimed is:

1. In a device for holding a movable member in adjusted positionsrelative to a stationary member, a frame forming a part of the movablemember and having a recess, a substantially U-shaped permanent magnetpositioned in the recess, said magnet having legs providing at theirfree ends a north pole and a south pole, a strip of non-magneticmaterial secured to the frame and having spaced recesses through whichthe legs pass, a pin projecting from the strip towards the magnet, and acoiled spring positioned by the pin and engaging the strip and themagnet to normally urge the magnet away from the strip, said magnetbeing adapted to cooperate with a strip of material attractable by themagnet, said last mentioned strip being mounted on the stationary memberadjacent the magnet and parallel to the non-magnetic strip.

2. In a device for holding a movable member in adjusted positionsrelative to a stationary member, a substantially U-shaped magnet freelymounted on the movable member and having a pair of legs providing attheir free ends a north pole and a south pole, a strip of non-magneticmaterial secured to the movable member and having a pair of spacedapertures through which the legs pass, and spring means engaging themagnet and strip to normally urge the magnet away from the strip, saidmagnet being adapted to cooperate with an armature mounted on thestationary member.

3. The structure set forth in claim 1 further characterized by means onthe magnet adapted to prevent direct contact therewith of the armatureto space the poles of the magnet therefrom.

4. The structure set forth in claim 3 further characterized by saidmeans comprising plates of non-magnetic material projecting beyond thepoles of the magnet.
